Description A novel technique, involving the hydrolysis of starch present in cassava
fibrous waste in shallow layers in stainlcss steel trays, is developed to
facilitate the use of higher slurry concentrations. The use of slurry
containing 30% solids. 4% sulphuric acid, 30 min saccharification time
at 121°C resulted in the complete conversion of the starch into reducing
sugars. The spent residue, after separation of the hydrolysate, contained
about 24% of the total sugars formed and these were recovered to
the extent of 90-94% by using a counter-current extraction technique.
A large scale saccarification of a 75 kg batch gave 75 I pooled hydrolysate
containing 15% reducing sugars. An overall process efficiency of
76.4% was observed with the fermentation of hydrolysate pooled with
the counter-current extract for alcohol production. However, fermentation
of the whole saccharified pulp without the separation of the
hydrolysate and acid-enzyme hydrolysis of the waste gave lower
efficiencies.
